Solution

DNA replication:

  1. In the process of DNA replication, the DNA makes multiple copies of itself.
  2. It is a biological polymerisation, which proceeds in the sequence of initiation, elongation, and termination.
  3. It is an enzyme-catalysed reaction. DNA Polymerase is the main enzyme in the replication process.

The function of DNA helicase in DNA replication:

  1. The main function of DNA helicase is to separate two strands of DNA for replication.
  2. Helicase is the enzyme, which unzips the DNA strands by breaking the hydrogen bonds between them. Thus, it helps in the formation of the replication fork.
